Vol. 4 | July 2025


This month our focus is on a new law that requires employees who are working on assessment or remediation under the supervision of a licensed mold professional to obtain the appropriate mold license or registration. The law goes into effect on September 1, 2025. 


89th Texas Legislature Passes Senate Bill 1255

Capitol Building Aerial

On June 20, 2025, Texas Governor Gregg Abbott signed into law Senate Bill (SB) 1255, relating to the regulation of mold assessors and remediators. SB1255, which goes into effect on September 1, 2025, makes changes to the current mold law, Chapter 1958 of the Occupations Code

What’s Changing?

  • SB1255 removes mycotoxins from the definition of “mold” in §1958.001(4).
  • Section 1958.002(b) has been amended to exclude the demolition of a structure after a fire or other disaster from the scope of regulated activities.
  • Section 1958.034(2) relating to the advisory board has a simple typographical correction: changing “or” to “of”.
  • Section 1598.102(b) of the Occupations Code is repealed.
    • The repealed text: “An employee of a license holder is not required to be licensed under this chapter to perform mold assessment or mold remediation while supervised by the license holder, as provided by rules adopted under Section 101

When do these changes take place?

  • SB 1255 will go into effect on September 1, 2025.

What do I need to do?

  • Employees who are not currently licensed or registered but are working on assessment or remediation under the supervision of a licensed mold professional will be required to obtain the appropriate mold license or registration. If your team members have not yet done so, we encourage you to begin the process to ensure they are properly credentialed.
  • Stay up to date with any changes through the TDLR mold program website (TDLR Mold Homepage) and the TDLR Mold monitor Email (Sign up to receive updates)

A Reminder About Licenses And Registrations

A common violation of the Mold program rules is not being able to present credentials when requested.

Rule 78.70(3): Licensees must “present to the department or the department's representative upon request any identification card, credential, or certificate issued by the department or the department's representative or designee.”

TDLR rules do not currently state whether credentials must be in physical or electronic form. But they must be presented upon request!
